Kid Cudi on 'One Tree Hill' and Other Bizarre Musician TV Cameos

Not every musician acts with the abandon and bravado of, say, Kanye West, but others can still make you scratch your head, like when they make bizarre cameos on random TV shows. Case and point: rapper Kid Cudi appearing on CW's yes-it's-still-on 'One Tree Hill.' We don't ask why musicians do it, but it's fun to catalog them, and there have been a lot of head-scratchers over the years. Some make sense, like Britney on 'Glee,' but others are just flat out bonkers like Boy George on 'The A-Team.' It's crazy and oddly amusing at the same time, so check out our list of the weirdest TV spots by musicians.

Kid Cudi on 'One Tree Hill'

For a show that routinely plays emo-music and country, Kid Cudi appearing on 'One Tree Hill' is pretty wacky.

The Flaming Lips on '90210'

The best part of this bizarre cameo is that people in the audience look semi-confused, just like the people watching the show from their couches.

Justin Bieber on 'CSI: Las Vegas'

Like it or not, Bieber is going to milk any chance he can to get on TV, even if he doesn't make a scary sociopath. He signed onto a multi-episode deal with 'CSI: Las Vegas' back in August.

Boy George on 'The A-Team'

All we can say is 'wow.' We wish Adam Lambert would one up Boy George and kick some terrorist butt in a cameo for '24.'

Alice Cooper on 'The Muppet Show'

This cameo was good weird. Only a real rock star would sing along with stuffed animals. You go, Alice Cooper.
